Jacob (Mormon)

Jacob (592 BC-420 BC) was a younger brother of the prophet Nephi and the author of the Book of Jacob, the third book in the Book of Mormon.

Biography
Jacob was born in the wilderness of the Arabian Peninsula, the son of Lehi and his wife Sariah, the younger brother of Laman, Lemuel, Nephi, and Sam, and the older brother of Joseph. The family travelled to the Americas aboard a ship built by Sam, and Jacob and Joseph were made priests by their brother Nephi. They preached to the fellow Nephites about the word of God, and Jacob gave three sermons: his first warned the people of knowing of God's commandments but defying them; his second decried pride, greed, and lust and also preached that the Lamanites were more morally righteous than the Nephites; and his third quoted the Parable of the Olive Tree. He wrote the Book of Mormon, which contained his sermons, and he died in 420 BC; he was succeeded as prophet by his son Enos.
